Conversion of Absolute Magnitude to Diameter for Minor Planets

You can change H and p in the text boxes above and recalculate.
The size of a minor planet was estimated using the following equation:

H is the absolute magnitude of the minor planet. This is the magnitude that it would have if it was 1 AU from
the Earth and 1 AU from the Sun while having a phase angle of 0 degrees. This is an impossible scenario but
it is just the definition of H. This is different than the absolute magnitude used for stars.
More Information

p is the geometric albedo of the minor planet. Perfect reflectors of light have A=1 and perfect absorbers have A=0.
Typical minor planets have a range of values: 0.05 < A < 0.25
